So I first installed cyanogen mod 7.0 correctly with CWM and I stupidly went into rom manager and installed the update to CWM and yesterday I recently booted into cwm but it failed and the whole tablet crashed and I have a black screen. The tablet wont turn on now completely black screen and I am worried that I fully bricked it. The tablet can also charge with the charging lights working currently I am letting it sit to drain power and try and restart it. I am sure its not a power issue but I have read that it may be stuck in apk mode and I tried to connect it to the computer and all that showed up on my computer was a unkown device not a apk with a yellow exclamation point so I cannot nv flash or install the drivers for the tablet... I tried on another computer also it wasn't showing up im on windows 7 by the way. Also, I tried to boot in apk and nothing happened I pushed the power and minus button... So could someone help me please It would be greatly appreciated!!!!!!!
